Music that sounds genuinly unhinged.

I allways love bands that sound like at least one of the members has a serious mental disorder. It definately makes the music more interesting. "Alien" by SYL, for example, was written when the singer/guitarist stopped taking his medication for his depression, and sounds ****ing emmense. In "In Utero", by Nirvana, it sounds like Cobain is having a mental breakdown.
